To all whom it may concern:

Be it known that I, EDWARD M. S'rILns, a

citizen of the United States, residing at Burlington, in the county ofDes Moines and State of Iowa, have invented certain new and usefulImprovements in Workholders for Slicing Machines, of which the followingis a specification.

The object of this invention is to provide a device of the class namedwhich shall be of improved construction and operation. The invention isexemplified in the combination and arrangement of parts shown in theaccompanying drawings and described in the following specification andit is more particularly pointed out in the appended claims.

In the drawings Fig. 1 is a rear elevation of one form of work-holderembodying thepresent invention.

Fig. 2 is a top plan view partly in section on line 2-2 of Fig. 1.

Fig. 3 is a fragmentary vertical section on the line 3-3 of Fig. 1. y

This application is a division of application Serial No. 243,022, filedJuly 2, 1918, patented December 20, 1921, No. 1,400,698.

In slicing machines of the usual form there is provided a reciprocatingtable shown at 10 in the drawings upon which a sliding work-holder ormeat plate 11 is mounted. The material to be sliced is placed on theplate 11 and held during-the slicing operation by a clamp or holder ofthe same form. It is usual to provide the edge of the talole 10 whichpassesadjacent the slicing knife during the slicing operation with acorrugated plate 12 which supports the portion of the meat or othermaterial being sliced projecting toward the slicing knife. After apieceof material has been almost completely sliced it is impossible tolonger clamp the material upon the meat plate 11. by a clamp which bearsupon the upper face of the material, and the pres ent invention providesmeans for engaging the face of the material opposite that from which theslices are being cut, for the purpose of forcing the material downwardlyupon the plate 12, so that its bottom surface may be firmly held againstthe plate while at the same time the rear surface is also grasped andheld inposition. Whenmeat" forwardly from the holder is held againstlateral pressure of the slicing knife by the corrugations in the plateon which it rests.

In the form of the invention shown in i I i this application thematerial is forced clownwardly into engagement with the corrugated plate12 by pivotal movement of engaging teeth'supported on the holder in amanner The plate 33 is provided with a plurality of slots 34 having lugs35 extending rearwardly from the edges thereof andpins or teeth 36supported on pivots 37 between the lugs 35. Each pin 36 is provided witha rearwardly projecting bifurcated portion 38 which engages a pin 39carried between spaced upright bars 40 arranged to move vertically inthe rear of the plate 33. The bars 40 are all connected by cross bars 41and 42 whichhave their ends guided in slots formed on the inner faces ofthe upright frame members 15. A pair of links 43 is pivoted to lugs44connected with the cross bar 41, and the upper ends of the links 43 areconnected with the prongs 45 of an operating lever 46 by pivot pins 47.The lever 46 is fulcrumed at 48 on lugs 49 carried by the upper crossbar 16 of the holder frame. A handle 50 may be attached to the bar 16for lifting the holder. The lever 46 and lugs 49 are provided withshoulde'rs5l and 52 for limiting the downward movement of the lever 46.In operation the lever 46 is pins 36 extend horizontally. The meat to besliced is then placed upon the uppersurfacc of the corrugated plate 12and prongs 36 are caused to penetrate the meat sufficiently to permitthe rear face of the meat to engage the front face of the plate 33. 46is then swung downwardly into the position shown in broken lines in Fig.3, which movement tilts the prongs 36 downwardly, as indicated in thatfigure, and thus draws the meat tightly into engagement with the frontface of the plate 33 and at the same held in its UPPBI'IIIOSl] positionsothat the The lever time torces it firmly into contact with the uppercorrugated surface of the plate 12. The lever 46 and links 43 arepreferably so related to one another that the lever will passdeadcenterjust'betore it reaches the limit of its downward movemenhand'inthis way the pins are locked in their downward position.

Iclalm:

1. A wort: holder for slicing machines comprising an upr'ght framehaving an abutment plate thereon, a plurality of teeth pivotally mountedon said frame and ariaiured to project forwardly from-said plate when insuitable position to receive material to be sliced as it IS movedagainst said plate, and rneans't'or shitting said teeth upon theirpivots in a directionsubstantially normal to the-longitudinal axis ofsaid plus to cause them to clamp said mater a]- against said plate. I

.2. A. work-holder for slicing machines, comprising anupright plate, aplurality oi substantially straight pins projecting torwardly from saidplate and pivotally mounted thereon, and means for shitting said pinsabout their pivots to cause them -to clamp material against said plate.

lna slicing machine, a work-supporting table, a work-holder mounted onsaid table and having an upright plate, Ia plurality of ivotallyimounted pins projecting forwardly from said plate inpos tion to entermaterial as itis moved against said plate, and means. for moving theforwart ends or said pins downwardly about their pivots and transverselyof their lengthto cause them to press material against'the upper face ofsaid work-supporting table and to clamp sa d material against saidplate.

i A work-holder tor shcmg machines,

' comprising a frame having stationary pivots thereon, work-engagingpins each separately mounted on one of said pivots, and a secondaryframe movably mounted on said first mentioned frame and ene ing saidpins to shift said pins upon their pivots and comprising a support formaterial to be tion sliced, a frame arranged in an upright posiabovesaid support, substant'iall straight pins pivotally mounted on saidtrains and movable into position to extend substantially horizontallytherefrom, and mechanism for tilting said pins downwardly into aninclined position to cause said pins to depress material engaged therebyagainst said work-support and against the face of said upright frame.

7. The combination with a work-support for slicing machines, .ofaWork-holder having an upright bearing surface arranged above saidsupport, worl -engaging pins plvotally mounted on said holder andprojecting trom the work-engaging face thereof sul'istantialjly :normalthereto when in work-receiving position, means for swinging said pinsdownwardly about thelr pivotal support on said Work-holder trom asubstantially horizontal to an inclined position, and means for lockingsaid pins in saidinclined position.

S. A meat end grip .l or slicing machines comprising a support ng frameha *ing an upright abutment plate, tines supported by said frame andprojecting at all times through openings in said plate to engagematerial to be held, andia-tine actuating frame member movable relativeto said supporting frame-and engaging said tines to cause them to gripmaterial and hold it against said abutment plate. 7
